PULVERIZING-IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 276,145, dated April 17', 1888.

` Application filed January 1G, 1883. (No model.) A

To all whom it may concern:

Be it known that I, T. MELLON ROGERS, of the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Pulverizing-Machine, of which the followy ing is a specification.

My invention relates to a class of pulverizing-machines in which the pulverizing-instrumentality isan independent vball or crushingsphere inclosed within a casing, and caused not only to rotate about its own axis, but also to revolve around a horizontal track in the casing, and in which said ball is permitted to move ing parts, Figure l is a vertical central longitudinalsectional elevation of an apparatus conveniently embodying my improvements.

Fig. 2 is a top plan view ofthe same, the section being supposed on the horizontal plane projected on the dotted line c a of Fig. l. Fig. 3 is a top plan view of the revolving oscillating disk, and Fig. 4 a bottoni plan view of the driving-disk.

In the drawings, A represents a housing of cylindriform contour, of any suitable construction, and provided with a base, B, in the form of a circumferential channel having outwardly-iiaring sides, of which sides the inner forms a cone, C, Which supports a vertical sleeve, D, and of which the outer is providedwith a circumferen tial screen, E, which over-han gs an eX- terior receiver, F. Within the channel formed in the base of the housing` is placed a horizontal ball-track, G, upon which the ball travels, and which is suitably retained in place in said channel.

tical sleeve is, as to its interior diameter, greater than that of the shaft, so as to forni a cylindriforin interspace or water-chamber. L, into which water is fed through the inlet M for the purpose of holding in suspension pulverized material and preventing it from having access to the stuffing-box of the shaft.

N is the lower bearing of the shaft, formed in the supporting frame-work Oof the housing.

P is a bevelgear suitably supported in the frame-work, and actuating the shaft to rot-ation.

Qis a revolving oscillating disk, preferably formed as a hollow cone surrounding the shaft, equipped as to its lower face with a revolving shoe-ring, Il., which bears upon the crushingsphere S, and at its upper extremity is conformed into a clutch-seat, T, of any preferred construction, but preferably of that represented 7o in the drawings. This clutch-seat is conformed to receive the rounded boss u of a revolving driving-disk, U, which is adapted to a squared extremity, j, of the shaft, so as to be compelled to revolve therewith, or is otherwise 'suitably 75 connected to such end, and which is provided with a clutch, ux, which engages with the clutch-seat T of the revolving oscillating disk.

V are lock-nuts threaded upon the upper extremity oi' the shaft, below its upper bearing, 8o and designed to force the driving-disk down upon the springs and oscillating disk with a predetermined pressure. Thedriving-diskearries a vertical depending cyliudriform diaphragm, X, which incloses the clutch between the disks, and also a series of vertical spiral springs,'\V, set between the under face of the driving-disk and the upper face ofthe revolving oscillating disk. These springs are held in position by bosses w y, respectively formed 9o on the under face ofthe driving-disk and the upper face of the oscillating disk.

Having thus described a preferred. construction of apparatus embodying my invention, its

operation will be readily understood. Motion is imparted to the driving-shaft through the bevel-gear, and through said shaft to the driving-disk, so as to cause the latter to take on the same motion of rotation as saidshaft. The revolution of the driving-disk, through the inroo strnmentality of the clutch, occasions the rev- Y elution of the oscillating disk and the shoering, which the latter carries, with the result that such revolution, coupled with the pressure exerted upon the ball (which is in place between the ball-track and shoe-ring) by the combined weight ofthe oscillating disk and driving-disk, and by the pressure ot' the compressed springs, occasions the revolution of said ball around the ball-track at a rate proportionate to the speed at which the shaft is driven. Materialfedthroughthehopperpasses between the vertical walls or sides of the casing and the depending diaphragm ofthe driving-disk and gravitates upon the ball-track, with the result that complete pulverization takes place between said ball-track and the t ball. The construction and adjustment of the oscillating dis tre of course such as to permit of its yieldin, .o enable the ball to travel over material of varying sizes which in its first revolution it is, perhaps, unable to crush. The pulverized material escapes through the circumferential screen into the exterior receiver, from whence it is withdrawn. It desired, sufficient water may be supplied to the waterchamber to overiow and assist in washing out the pulverized material through the screen.

The springs are made of any suitable material, may be applied in any number, and, it'

desired, of a construction other than the spiral construction shown, although I believe the latter to be the more available. Ihey are ofsuch dimensions and material as to exert a predetermined pressure, calculable in terms of the power necessary to crush certain kinds of material to a certain size. The pressure upon the ball is, as stated, due to the action ot' the disks, springs, and lock-nuts, as herein fully explained.

As will be readily understood, the shaft may be driven from above the casing rather than from'below, and the form ot' the casing, aswell as of the disks, may be varied to an extent not interfering with that essential construction ot' the device which permits ot' the use of a horizontal ball-track, and of a pressure which is always directed in a vertical direction downward upon the crushing-sphere. I believe, however, that the construction represented is simple, inexpensive, and practical.

It is ot' advantage to line the base ot' the casing as to its 'flaring sides, which encircle the ball-track, with chilled iron, steel, or other facing material adapted to resists the attrition Aofthe pnlverized particles. Ifdesired, a screen may be adapted to the cone ofthe base, so as to enable a central discharge.

It is competent for me to employ more than one sphere, it' I so desire, although I prefer to use but one.

It is obvious that while I have specied a housing of specilic contour and construction,

yet, as this housing vsimply forms a means of t supporting and containing the several assembled members of the apparatus, other forms of-housing or casing may be substituted in its stead, andf that, if desired, the housing need not be inclosed, but be simply of such construction and arrangement as provides for the support of the ball-track and screen. I have also recited lock-nuts threaded upon the upper extremity ofthe shaft as a means for controlling the set and pressure of the disks and springs with respect to the crushing sphere. Other devices operating to the same result may of course be substituted in their stead. I simply instance lock-nuts as a cheap and convenient contrivance for the purpose. I have also described the oscillatory disk as provided with a shoe-ring. It is manifestly possible, however, to dispense with the shoe-ring, and to so conform and adjust said disk as to tread direct upon the crushing-sphere.

Having now described my invention, I claim and desire to secure by Letters Patent- I. In a pulverizing-niachine, the following instrumentalities in combination: first, ahousing provided with a horizontal ball track; second, an independent ball or crushingsphere; third, a revoluble oscillatory disk; fourth, a driving-disk adapted to actuate to revolution said oscillatorydisk; fifth, springs interposed between the driving-disk and the oscillatory disk; and, sixth, suitable means for oceasioning the revolution ot' the drivingdisk.

2. In a pulverizingmachine, in combination with a housing embodying a horizontal ball-track, a shaft verticallyjournaled through said casing, an oscillatory revoluble disk applied to said shat't and adapted to bear upon a crushing-sphere traveling upon said balltrack, a crushing-spliere, a driving-disk adapted to actuate said oscillatory disk, and means, substantially such as set forth, for adjusting the vertical set ofthe disks with respect to the sphere and their'consequent pressure thereupon, substantially as described.

3. In a machine of the class herein recited, the combination of' the driving disk, the springs, the revoluble oscillatory disk, and a depending diaphragm adapted to inclose the springs, as and for the purposes specified.

4. In a pulverizing-machine, the combination of a driving-shaft, a revoluble oscillatory disk surrounding said shaft and provided with a clutch-seat, a driving-disk applied to said shaft, so as to be incapable ot' oscillation, and provided with a clutch adapted to the clutch-seat in the oscillatory disk, springs interposed between the disks, and means, substantially 'as set forth, for adjusting the set ofthe driving-disk with respect to the springs and oscillatory disk, substantially as set forth.

In testimony whereof I have hereunto signed my name this 13th day of January, A. D. 1883.

T. MELLON ROGERS.
